Ime, with DDD, degenerative disc disorder, the discs dry out and start to collapse. The severity varies between individuals, and 75% of the population have it to some extent.
Spasms, (extreme pain) can result. Usually passes into a constant dull ache within a week. Pain killers and tens machine seem to be the only things that work for me for the spasms. Dull ache has to be lived with.
Thing is, finding out what causes your particular issues. As Diagnosing someone else's cure is dodgy.
But if its a spasm, you should be able to feel the muscle that's painful and force it to relax. Not by massage so much, but squeezing it, pressing on it, and generally forcing the blood out of the muscle that's causing the agro.
If its nerve based, its a case of finding a comfortable position and paying a professional to free off the skeletal structure that's out if position, once the pain dies down a little.
Hth somehow.
